Answer:
w =
Step-by-step explanation:
p = 2l + 2w Subtract 2l from both sides of the equation
p - 2l = 2p Divide both sides by 2
= w
The intersection points of the equations represents; C: The time when the height of the ball and the bird are the same.
We are given;
The height of the baseball over time:
h = -16t² + 65t
The height of the bird over time:
h = 8t + 20
The intersection point will be the value of t when; 8t + 20 = -16t² + 65
Rearranging gives;
16t² + 8t - 45 = 0
Using online quadratic equation calculator gives us;
t = -1.94 s or t = 1.44 s
Now, since both equations measure height vs time, it means that the points of intersection tell us the time when the height of the ball and the bird are the same.

Answer:
f(2) = -1
Step-by-step explanation:
Looking at the graph, there appears to be two points at x = 2. However, looking more closely, we see that the point (2, 4) is empty; this means the graph goes up to this point but does not hit this point.
The point (2, -1) is filled in; this means the graph hits this point.
